To understand why some objects sink while other objects float, scientists look at 3 variables: _______________, _______________, and _______________.
_______________ is a noncontact force that attracts an object to the center of the Earth.
_______________ is a measurement of how compact an object is, or the ratio of mass to volume.
_______________ is a force that pushes up on objects that are in a fluid, such as water.
The density of pure water is equal to _______________.
In general, if an object has an overall density less than 1.00 g/mL it will _______________in water.
If an object has an overall density greater than 1.00 g/mL it will _______________in water.
_______________ principle explains why objects with a density greater than water’s can still float.
In basic terms, Archimedes’ principle states that if the mass of water displaced by an object is _______________ __ _______________ than the object’s mass, it will float.
The reason why a steel boat floats in water but a steel nail does not is that the boat’s unique _______________ displaces a larger amount of water compared to the nail.
